Hint:
Use linspace () to create t. Then
y = amplitude * sin(2 * pi * freq * t)
Come back with your code if you still have trouble.

Create two sinusoidal waves, one with frequency=7 Hz and the other with 40 Hz for 1001 data points.
Assume the sampling frequency (Fs) is 250 Hz and both signals have same amplitude. Plot these
signals using the subplot function.
